SPEUJEFICATION tanning part of Letters Patent No. 783,8'M, dated February as, root.

Application filed October 19,1904. Serial No. 229,193.

T0 (at whom it may cancer "ml Be it known that it, HENRY D. iinn'ra, a citizen of the Uni ted States, residing at Fremont, in the county of Mahaska, lzltate oi lowa, have invented certain new and useful improvements in Adjustable Bearings; and l do hereby declare the following to he a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to hearings, and more particularly to shaft-hearings, and has for its DDJBGl) to provide a hearing which may be ad- ;ulsted in a simple and rapid manner to com- Ipensate for wear of the parts.

"Other objects and advantages will he'ap'parent from the following description, and it will be understood that variations in the form and proportion shown and described may he made and that any suitablematerials may he used without departing from the spirit of the invention,

in the drawings forming a part of this speci lication, and in which like numerals of retorence indicate similar partsinfthe several views, liignre 1 is a'vertical longitudinal sec-- tion or the hearing. Fig. an a horizontal longitudinal section. Fig. 3 is a transverse section talren on line 3 3 0t Fig. i: Fig. i is a side elevation of the complete hearin 5 is a horizontal longitudinal section a modification in which the wings and are omitted.

Referring now to the drawings, there is shown a snpgih'iting-hrackct 5., through the recesses head 6 of which there is formed a passage and at one'end of this passage there is an in weirdly-directed flangeiii, which is threaded on its inner race as shown at 9. l ormed at tiltinmetrically opposite points in the sides of the passage 7 are wedge-shaped recesses 10, the

vertical sidewalls l1 oi which slant outwardly from the walls of the passage l at points adjacent to the end oi the passage which lies away t'rom the flange 8, the recesses it) thus lying with their major ends in the direction oi? the flange and with the walls oi these ends extending horizontally. its usual, the head 6 ot' the snpportinghrachet consists oi two portions 6' and 6", which are halted together l sage said hushinghaving tapered portions cor- 1W showing the recesses 10.

and in the present instance the division hetween these two portions extends horizontally bushing 12, which is divided vertically into two portions 152" and 152", each ot these portions having a wedge-shaped wing 13 extend ing laterally therefrom and lying in one of Each of the sections of the bushing of course has a liingitudinally-eatending arcuate groove it in its inner face these two grooves together forming a passage for the reception of the shaft 15.

Engaged with the threads 9 of the flange 8 is a cylindrical follower 16 having a central passage 17, in which the shaft is engaged, and at its outer end this follower is provided with an angular llange 118, which may he grasped with a wrench, the inner end of the t'ollower resting against the bushing 12, and it will he understood that this follower may he operated to move the hashing longitudinally with- "in the head, the wings 13 at the same time causing the sections of the hashing to move inwardly and closely fit the shaft.

Engaged with the follower outwardly of the flange 8 is a loch-not in, which may be moved toim pings against'the end or the head and against a hand 20, mounted thereon to hold the ioh lower against movement Loosely engaged with the shalt i5 at the opposite side of the head from the tollower is a collar ill, having a set-screw 93% therein, which may he operated to bear against the shaft and to prevent rotation oi the collar thereon. This collar may he moved on the shalt to rest against the end of the hashing, and thus prevert end thrust.

in Fig. 'a there is shown a modification in which hoth the passage 'i' and thehnshing iii are angular in cross'scctions, the passage and hashing losing correspondingly tapered longitudinally away trom the tlange 8., the recesses l0 and wings 13 being thus omitted" What is claimed is-- in in a hearing, the combination with ahead having a passage therethrough. said passage having tapered portions, ot a hashing meloding two sections slidahly disposed in the pas responding to the tapered portions of the passage, a follower arranged for movement to bearagainst the bushing and move the latter in the direction of the minor ends of the tapered portions, means for holding the follower at different points of its movement, a shaft revolubly engaged in the bushing, a collar revolubl y mounted upon the shaft and arranged for movement to lie against the end of the bushing and means for holding the collar against rotation upon the shaft.

2. In a device of the class described,the combination with a bracket having ahead provided with a passage, said passage having tapered portions, said head having an inwardlydirected interiorly-threaded flange at one end of its passage, abushing including two sec- 1 tlons slldabl y disposed in the passage and havl head to prevent movement of the follower.

In testim on y whereof I aflix my signature in 3 presence of two witnesses.
